Mature Bouganville taking over.

I'm really liking this place, I've got questions all over the forums. J
I have a stunning Bougainville (color) quite mature having made it's way down thru a 4' rockwall/planting bed and 2" roots dislodging the paved walkway and probably attacking the Lava rock wall in secret.

I have several reasons to want to kill it, think of it often as the of trimming and hauling away wicked thorns alone are so not fun. But it is gorgeous and frankly I've been unable to kill some much smaller Bougie after 7 years of trying. This one is an upright and has quite the sturdy trunk at least 1' wide. Doubt I can kill it, and no way to get any equipment in there to dig it out.
I've pulled up the broken walkway and chopped on the roots for two years now simply creating new branches all over the ground.

How could anyone want to kill this tropical beauty, especially with chemicals??? Think of Mother Earth & be thankful you can grow it there. It's part of what makes Hawaii gorgeous. Here our growing season is soooo short, things get planted & before you know it, it's time to yank it from the ground or it freezes! If it was planted, it's meant to be there, let it flourish. God Bless y'all!
